SUMMARY OF INVENTION Technical Problem

However, the above carry-on bag may not be able to suppress the motion of the bag effectively enough. For example, the carry-on bag has a possibility of rotating about the handle lever and shifting from the top of the suitcase.

It is an object of the invention to provide a carry-on bag capable of suppressing shaking of the bag body on a suitcase.

Solution to Problem

A carry-on bag according to one aspect of the present invention includes: a bag body; a belt strap for a handle extending in a first direction and configured to form a first opening between the belt strap for a handle and a side surface of the bag body for allowing a retractable handle lever of a suitcase to pass through in a second direction crossing the first direction; and a belt strap for a grip extending in a third direction crossing the first and second directions and configured to form a second opening between the belt strap for a grip and a bottom surface of the bag body for allowing a grip of the suitcase to pass through in the first direction, wherein the belt strap for a grip has an opening and closing structure allowing the belt strap for a grip to open and close to the bag body while allowing the grip to pass through the second opening.

According to the above aspect, when the handle lever of a suitcase is inserted into the belt strap for a handle and the grip of the suitcase is inserted into the belt strap for a grip, it is possible to inhibit shaking of the bag body on a suitcase due to the synergistic effect of the belt strap for a handle and the belt strap for a grip with a simple structure. That is, it is possible to prevent the carry-on bag from pitching, rocking left and right, or rocking back and forth. The above aspect also provides an advantage of eliminating the time and complexity required to attach the carry-on bag to a suitcase.

EMBODIMENTS OF THE INVENTION

The structure of the carry-on bag 1 will be described with reference to the drawings. Hereinafter, the left side, the right side, the upper side, the lower side, the front side of the paper surface, and the rear side of the paper surface of FIG. 1(a) correspond to the rear side, the front side, the upper side, the lower side, the left side, and the right side of the carry-on bag 1, respectively. Note that the left-right direction, the up-down direction, and the front-rear direction correspond to the first direction, the second direction, and the third direction of the present invention, respectively. FIG. 1(a) is a cross-sectional view of the carry-on bag 1 of the invention. FIG. 1(b) is a rear view of the carry-on bag 1 of the present invention.

First Embodiment

As shown in FIG. 1 , the carry-on bag 1 has a bag body 20. The inside of the bag body 20 is a storage space. The top of the bag body 20 has an opening/closing portion (not shown) that can be opened and closed. A handle 3 that can be gripped by a user is provided on the upper surface of the bag body 20. Note that the position where the handle 3 is provided is not limited to the upper surface, and the handle 3 may be provided on any of the left, right, front, or rear surface or no handle may be provided. The handle 3 may include a plurality of handles. A belt strap 2 for a handle is provided on the rear surface (back) of the bag body 20. The belt strap 2 for a handle extends in the left-right direction. Both left and right ends 5 of the belt strap 2 for a handle are sewn to the bag body 20. Thus, an opening (first opening of the present invention) is formed between the rear surface of the bag body 20 and the belt strap 2 for a handle penetrating in the vertical direction.

Further, a belt strap 4 for a grip is provided on the underside surface (bottom) of the bag body 20. The belt strap 4 for a grip extends in the front-rear direction. The belt strap 4 for a grip is configured with, for example, two strap bands 4 a, 4 b, that is, the strap band 4 a and the strap band 4 b are respective parts of the belt strap 4 for a grip and can be opened and closed with respect to the lower surface of the bag body 20. A rear edge 41 of the strap band 4 a and a front edge 42 of the strap band 4 b are sewn to the lower surface of the bag body 20. Note that one or both of the rear edge 41 of the strap band 4 a and the front edge 42 of the strap band 4 b may be unsewn to the lower surface of the bag body 20 but may be adhered with an adhesive or may have a structure detachable from the bag body 20 with a fastener or the like.

As shown in FIG. 2 , a fastener 9 is provided at the front edge of the strap band 4 a and the rear edge of the strap band 4 b. When the front edge of the strap band 4 a and the rear edge of the strap band 4 b are bound together by the fastener 9, the belt strap 4 for a grip is closed to the lower surface of the bag body 20. With the front edge of the strap band 4 a and the rear edge of the strap band 4 b bound together, i.e., when the belt strap 4 for a grip is closed against the lower surface of the bag body 20, an opening (second opening of the present invention) penetrating in the left-right direction is formed between the lower surface of the bag body 20 and the belt strap 4 for a grip. When the connection by the fastener 9 is released, the belt strap 4 for a grip is opened to the lower surface of the bag body 20.

It is also possible to substantially eliminate the strap band 4 b of the belt strap 4 for a grip and to use a fabric portion (not shown) with the fastener 9 itself as a substitute. That is, the fastener 9 may be directly attached to the bottom of the bag body 20 and the strap band 4 a of the belt strap 4 for a grip may be coupled with the fabric portion of that fastener 9. As a result, the number of components for the belt strap 4 for a grip can be reduced.

The structure of the suitcase 6 and a method of attaching the carry-on bag 1 to the suitcase 6 will be described with reference to FIG. 3 . FIGS. 3(a) and 3(b) are diagrams illustrating the carry-on bag 1 of the present invention attached to the conventional suitcase 6. Hereinafter, the left side, the right side, the upper side, the lower side, the front side of the paper surface, and the back side of the paper surface of FIG. 3(a) correspond to the rear side, the front side, the upper side, the lower side, the left side, and the right side of the suitcase 6, respectively. FIG. 3(b) is a rear view of the carry-on bag 1 of the present invention attached to the conventional travel suitcase 6.

The represented suitcase 6 has casters 13, a handle lever 7, and a grip 8. The plurality of casters 13 are provided on the bottom surface (lower surface) of the suitcase 6. The handle lever 7 is retractable in the direction of the arrows (vertical direction). The user can move the suitcase 6 by gripping the upper end of the handle lever 7 and moving, thus rotating the casters 13. The grip 8 extends in the left-right direction and forms an opening that penetrates in the front-rear direction between the grip 8 and the upper surface of the suitcase 6. The user can carry the suitcase 6 by putting his/her hand into the opening and gripping the grip 8.

The user places the carry-on bag 1 on the upper surface of the suitcase 6 for use. Specifically, the user passes the handle lever 7 through the opening between the rear surface of the bag body 20 and the belt strap 2 for a handle from below. Further, the user releases the binding of the fastener 9 and wraps the grip 8 with the opened strap band 4 a of the belt strap 4 for a grip, and then joins the strap band 4 a to the strap band 4 b with the fastener 9. As a result, the grip 8 of the suitcase 6 passes through the opening between the belt strap 4 for a grip and the bag body 20 in the left-right direction. When carrying the carry-on bag 1 itself, the user grips, for example, the handle 3 and holds the carry-on bag 1 so that the lower surface (bottom surface) of the bag body 20 faces downward.

Second Embodiment

The embodiment shown in FIG. 4 is a second embodiment in which the belt strap 4 for a grip is composed of a plurality of strap bands, e.g., three strap bands arranged in the horizontal direction. It is a structure in which the strap bands 4 a are arbitrarily selectively selected for connection according to the horizontal spacing of the grip 8 of the suitcase 6. That is, if the length of the grip 8 in the left-right direction is short, the central strap band 4 a is used, and if it is long, the three strap bands 4 a are used. As a result, it is possible to cover a variety of spacing within the grip 8 in the left-right direction. In this example, instead of the fastener 9, a raised hook-and-loop fastener 10, such as a Magic Tape® fastener and a Velcro® fastener, may be employed for the connection between the strap bands 4 a and 4 b. For example, as shown in FIG. 4A, the one strap band 4 b may extend in the horizontal direction from the left side of the leftmost strap band 4 a to the right side of the rightmost strap band 4 a. Also, as shown in FIG. 4(b), the strap bands 4 b may be arranged side by side in the left-right direction as many as the strap bands 4 a. Furthermore, instead of the raised hook-and-loop fastener 10, it is possible to use a hook-and-loop fastener, a magnet sheet (a hook-and-loop magnetic tape), or the like as a substitute.

Third Embodiment

The embodiment of FIG. 5 is the third embodiment using hooks 11 instead of the fasteners 9 described above. Alternatively, the strap band 4 b may be eliminated and the hook 11 may be attached directly to the bottom surface (lower surface) of the bag body 20 to connect to the strap band 4 a of the belt strap 4 for a grip. As a result, the number of components for the belt strap 4 for a grip can be reduced. A single hook, or the like may be employed in place of the hooks 11. Also, although not shown in the drawings, the width (the length in the front-rear direction) of the belt strap 4 for a grip may be increased to allow the extended portion to wrap around to part of the rear surface (on the side of the belt strap 2 for a handle) and/or the front surface of the bag body 20, and the extended part may be attached to a fastener, a hook, etc. As a result, the opening and closing of the fastener or the like is facilitated by allowing the opening and closing to be performed on the side surface of the bag body 20. In short, the majority of the belt strap 4 for a grip is arranged on the bottom surface of the bag body 20.

Modification

Of course, it is also possible to employ any combination of the first to the third embodiments described above with the carry-on bag 1. In any embodiment, it is desirable to use a material of the belt strap 4 for a grip having strength and stretchability, but it is needless to say that it does not have to be so. The material of the belt strap 4 for a grip is not limited to cloth, leather, vinyl, rubber cordage, metal, metal chain, plastic, or the like. Further, it is desirable to select the material, design pattern, color, and the like of the belt strap 4 for a grip same as those of the bag body 20 in order to improve the aesthetics, but needless to say, it is not mandatory. It should be noted that if the belt strap 4 for a grip of the present invention is used for attachment to the seat of a bench, theft of the carry-on bag 1 can be effectively prevented.

Note that the number of the belt strap 4 for a grip may be one. That is, the belt strap 4 for a grip may be configured by any one of the strap bands 4 a, 4 b, in other words, the strap band 4 a may be the entire belt strap 4 for a grip, for example. In this case, at least one of the front and rear ends of the belt strap 4 for a grip may be detachable from the bag body 20. That is, the belt strap 4 for a grip may be completely separated from the bag body 20 as long as the front and rear ends of the belt strap 4 for a grip are detachable from the bag body 20. The attachment/detachment structure (opening/closing structure) of the belt strap 4 for a grip is not limited to the fastener 9, the hooks 11, the single hook, buttons, magnet sheets, and the like. The belt strap 4 for a grip in the left-right direction may have an arbitrary width, which may be longer or shorter than the length of the belt strap 4 for a grip in the front-rear direction while the width is preferably shorter than the length of the grip 8 in the left-right direction.

Although illustration is omitted, two, for example, of the belt straps 4 for a grip may be provided, and when these two belt straps 4 for a grip are closed with respect to the bag body 20, they may be provided to cross each other on the lower side of the bottom surface of the bag body 20, for example, at the center of the bottom surface of the main body 20, that is, in an “X” shape when viewed from the bottom. That is, one belt strap 4 for a grip may extend from the right side of the center in the left-right direction at the front end of the bottom surface of the bag body 20 to the left side of the center in the left-right direction at the rear end of the bottom surface of the bag body 20, and another belt strap 4 for a grip may extend from the left side of the center in the left-right direction at the front end of the bottom surface of the bag body 20 to the right side of the center in the left-right direction at the rear end of the bottom surface of the bag body 20.

In addition, given that the two belt straps 4 for a grip that cross on the lower side of the bottom surface of the bag body 20 are referred to as one set of belt straps for a grip, a plurality of sets of the belt straps for a grip may be arranged side by side in the left-right direction.

Furthermore, the two belt straps 4 for a grip that cross on the lower side of the bottom surface of the bag body 20 may each be composed of one strap band or may be composed of a plurality (for example, two) of strap bands. Specifically, the multiple strap bands may extend parallel to each other or may extend so as to cross on the lower side of the center of the bottom surface of the bag body 20. That is, a plurality of “X” shaped strap bands having different angles at their intersections when viewed from the bottom may be provided as two (two sets) of the belt straps 4 for a grip.

In addition to the two belt straps 4 for a grip that cross on the lower side of the bottom surface of the bag body 20 above, an additional belt strap 4 for a grip may be provided that extends in the front-back direction and crosses at the point where the two belt straps 4 for a grip above cross each other. Furthermore, such a belt strap 4 for a grip extending in the front-rear direction and crossing at the point where the two belt straps 4 for a grip cross each other may be not limited to one but a plurality (for example, two) of the belt straps 4 for a grip may be arranged side by side in the left-right direction. When the plurality of the belt straps are arranged in the left-right direction, all of them may be arranged between the left end and the right end of the one set of the belt straps for a grip, or may be arranged to the left of the left end and to the right of the right end.

The two belt straps 4 for a grip crossing on the lower side of the bottom surface of the bag body 20, the grip straps 4 extending in the front-rear direction and crossing at the point where the two belt straps 4 for a grip cross each other, etc., may each be composed of one strap band or may be composed of two strap bands, such as the band 4 a and the band 4 b.

Still in addition, the belt strap 4 for a grip may be composed of three of the strap bands 4 a, 4 b and a connecting band. In this case, a fastener 9 or the like is provided at one end as well as the other end of the connecting band, and the fastener 9 at the front edge of the strap band 4 a is coupled with the fastener 9 at the rear edge of the connecting band, and the fastener 9 at the rear edge of the strap band 4 b is coupled with the fastener 9 at the front edge of the connecting band. In this case, the fastener 9 at the front edge of the strap band 4 a may further be coupled to the fastener 9 at the rear edge of the strap band 4 b. According to this configuration, the user can adjust the length of the belt strap 4 for a grip in the front-rear direction depending on whether or not the connecting band is used. That is, such a usage is provided not to use the connecting belt when it is desired to firmly fix the carry-on bag 1 on the suitcase 6, and in other cases, to use the connecting belt. Note that, when the plurality of belt strap 4 for a grip are provided, they may be partially composed of the three of the strap bands 4 a, 4 b and the connecting strap or they may be entirely composed of the three of the strap bands 4 a, 4 b and the connecting strap.

Also, the belt strap 4 for a grip may be provided obliquely with respect to the bottom surface of the bag body 20. That is, only either one of the one set of the belt straps 4 for a grip may be provided.

Further, the shape of the belt strap 4 for a grip is not limited to trapezoid, triangle, rhombus, star, circle, pentagon, and the like. When the plurality of belt straps 4 for a grip are provided, each belt strap 4 for a grip may have a different shape.

Also, the belt strap 4 for a grip may be one or a plurality of cords.

For example, if the belt strap 4 for a grip is composed of one strap band and its front end is detachable from the bag body 20, an auxiliary member that is thinner than the length of the belt strap 4 for a grip in the left-right direction may be provided on the underside of the front end (the opposite side of the belt strap 4 for a grip to the bag body 20). The auxiliary member is a band, cord, or the like, and the auxiliary member and the belt strap 4 for a grip are connected to each other at the connecting portion by an adhesive, stitching, or the like. Therefore, the auxiliary member can pivot freely with the connecting portion to the front end of the belt strap 4 for a grip as a fulcrum. The end of the auxiliary member opposite to the connecting portion is provided with a detachable portion on the auxiliary member side. On the rear side of the belt strap 4 for a grip from the connecting portion, a strap band side detachable portion is provided where the auxiliary member side detachable portion can be attached and detached. The auxiliary member side detachable portion and the strap side detachable portion are detachable from each other with a fastener, buttons, hooks, or the like. Further, the auxiliary member has a ring shape so that a user's finger can be hooked. In this case, for attaching the carry-on bag 1 to the suitcase 6, the user can hook a finger in the ring of the auxiliary member and pass the belt strap 4 for a grip through the lower side of the grip 8 of the suitcase 6. Thus, attachment and detachment of the carry-on bag 1 to and from the suitcase 6 are facilitated. After attaching the carry-on bag 1 to the suitcase 6 or when carrying the carry-on bag 1 alone, the two ends of the auxiliary member are fixed to the belt strap 4 for a grip by the strap band side detachable portion and the connecting portion by attaching the auxiliary member side detachable portion to the strap band side detachable portion. Therefore, the auxiliary member can be restrained from becoming an obstacle and does not detract from the decorativeness in view of the aesthetics. In addition, the shape of the auxiliary member may be in a shape other than the ring shape, and the auxiliary member side detachable portion and the strap band side detachable portion may be omitted. Further, a hole may be provided in the connecting portion of the belt strap 4 for a grip, and the auxiliary member may be threaded through the hole. In this case, both ends of the auxiliary member may be larger than the inner diameter of the hole so as not to come out of the hole. The auxiliary member may be provided on the upper surface of the belt strap 4 for a grip (the surface facing the bag body 20). In this case, the auxiliary member can be stored between the belt strap 4 for a grip and the bottom surface of the bag body 20 even without the auxiliary member side detachable portion and the strap band side detachable portion. Further, when the rear end of the belt strap 4 for a grip is detachable from the bag body 20, the auxiliary member may be provided at the rear end of the belt strap 4 for a grip. When the plurality of belt straps 4 for a grip are provided, the auxiliary member may be provided on each belt strap 4 for a grip, or may be provided only on some of them. Further, the material of the auxiliary member is not limited to cloth, leather, vinyl, rubber cordage, metal, metal chain, plastic, or the like. In addition, it is desirable to select the auxiliary member made of the same material, design pattern, color, and the like as those of the bag body 20 or the belt strap 4 for a grip to improve the aesthetics, but needless to say, it is not mandatory.

Effect

By providing the belt strap 4 for a grip on the carry-on bag 1, the bag main body 20 can be firmly fixed to the suitcase 6, that is, when the carry-on bag 1 is attached to the suitcase 6, the belt strap 2 for a handle inhibits the swinging of the bag body 20 in the front-rear direction, and further, the belt strap 2 for a handle can inhibit rotation of the bag body 20 about the axis extending in the left-right direction and rotation of the bag body 20 about the axis extending in the front-rear direction, and in addition, the belt strap 4 for a grip suppresses vertical swinging, and the belt strap 4 for a grip can inhibit rotation of the bag body 20 about the axis extending vertically and rotation of the bag body 20 about the axis extending in the front-rear direction are controlled by the grip strap 4 as well, and synergistically, rotation in all directions of the front and rear, up and down, and left and right, that is, rocking of the bag body 20 on the suitcase 6 can be suppressed. Therefore, it is possible to improve the activeness, promptness, security, etc. of travel and the like.

Remarks

FIGS. 6(a) and 6(b) are explanatory diagrams of an example in which a conventional carry-on bag 100 is tied to a suitcase 6 with a rubber cord 12 (broken line). It can be seen that this conventional method and mechanism have drawbacks, such as increased cumbersomeness of hanging the rubber cord 12 and impairing the aesthetic appearance.
